DISJOINTABLE PACKING-CASE.

V Specification of Letters Patent.

Patented March 19, 1907.

Application filed October 18. 1905- Serial No. 283,349.

I'o all whom it may concern.:

Be it known that I, THOMAS KRISTIAN OVERGAARD, a subject of the King of weden, and a resident of Villa Tomsbo, Orgryte, Gothenburg, in the Kingdom of Sweden, have invented certain new and useful Improveniente in Disjointable Packing-Cases, of which the following is a specification, reference being had therein to the accompanying drawing.

'Ihis invention relates to improvements in such disjointable packing-cases which for the connecting of the case parts are provided with hinge-pieces extending along the edges of the case parts and connected by a rod.

A characteristic feature of this invention consists in the said hinge-pieces, which preferably are formed from folded strips of metal sheet, being inserted to such an extent in grooves provided in the edges of the case parts that when the case parts are to be connected they engage each other, so that the channel formed by the said pieces is considerably narrower than the rod connecting the parts. Owing to this arrangement the advantage is gained that when the pointed rod is pushed into the said channel it will draw the case parts together more closely than is the case in disjomtable cases of this class hitherto used.

vAnother characteristic feature consists in .the said connecting-rod being provided with barbs directed toward the head of the rod, so that when the case is to be disjointed the rod must be drawn out in the same direction as it was inserted, which can only be done' after the said head has bee] cut off. In this manner a simple and reliable sealing of the box is effected.

In the accompanyin drawing, Figure 1 is a perspective view o a packing-case arranged in' accordance with this invention with the cover and the connecting-rod. Fig.

` 2 is a cross-section of the ends of two case parts-the cover and one of the end walls, for instance-which are to be connected. Fig. 3 shows the parts put together, the connecting-rod being not yet inserted, and Fig. 4 shows the position of the parts after the said rod has been inserted.

In the edges of two neighboringcase partsfor example, the cover 1 and one of lthe, rend walls 2-rims are provided, one of which is V- shaped and the other rectangular, as shown in Fig. 2. From the said rims grooves 3 extend inward in the boards in which the hingepieces 4 5 are inserted, which extend along the whole or substantially the whole edge of the said parts. The rims when brought together form a closed chamber in which the hinge-pieces, are protected. Each of the said hinge-pieces is preferably made of a folded strip-of metal sheet suitably stamped, v

held in the grooves 3 by nails or screws, as shown. When the case parts are put together, the different loopsl of the hinge-pieces 4 and 5 will engage each other only partially, sothat the channel 6, Fig. 3, formed by the same, is considerably narrower than the rod 7, adapted to be insertedinto the said channel. One end of the said Arod is pointed, so as to allow of it being pushed into the channel 6 in spite of its comparatively great diameter. When the rod is inserted, the hin e-pieces are forced one into the-other, as s own in Fig. 4. If the case parts should not fit perfectly together, Fig. 3, the rod 7 will firmly draw the parts togetherfand even if the case rod is, however, narrower than the rod, so that the rod draws the hinge-pieces, and consequently also the case parts, firmly together. The rod 7 may be provided with a head 9 and barbs 8, directed toward the said head, preventing the rod to be drawn out. In this manner the rod serves as a locking device, as the rod cannot be drawn out unless the head is out off. After the head has been cut off the rod is p'ushed or drawn out in the same -direction in which it was inserted.

Although only the cover and the end walls of the case are shown connected in the manner stated, it should, however, be understood that all case parts are connected by the means described, so that the ease may be entirely .parts should 'l'it exactly the channel 6 for the disjointed, and thus requires the smallest possible space when stored, and may, moreover, be easily put together when it 1s to be used.

Having now described my invention, what I claim as new, and desire to secure by Lety IOS IIO

said rod, the rims of two adjacent case parts forming closed chambers for protecting the hinge, substantially as described and for the purpose set forth.

2. In,disjointable packing-cases the combination of hinge-pieces mounted in rims in the edges of the case parts and extending along the same and inserted for such an extent in grooves extending into the case parts from the said rims, that the hinge-pieces at the edges of two adjacent case parts'when put together engage each other only4 to such an extent that the channel for the connectingrod is considerably narrower than the said rod, and barbs provided on the connectingrod and directedtoward the head of the rod, substantially as described and for the purpose set forth.

3. In disjointable packing-cases thecombination of hinge-pieces mounted in rims in the edges of the case parts and extending the rims of two adjacent case parts forming closed chambers, protecting the hinge, substantially as described and for the purpose set forth.

In witness whereof I have hereunto signed my name7 this 6th day of October, 1905, in thepresence of two subscribing Witnesses.
